On Aug. 28, the spouses celebrated two decades of marital bliss by renewing their vows at LIO Ibiza by Pacha in Ibiza, Spain. French house music producer and DJ David -- known for hit songs like "Memories" (featuring Kid Cudi), "Titanium" (featuring Sia) and "When Loves Takes Over" (featuring Kelly Rowland) -- looked dapper in a traditional black tuxedo and a bowtie, while his wife wore a pleated white mini-dress and a tiara in her hair.

The outdoor, waterfront ceremony was attended by several A-list musicians, models and deejays, including Naomi Campbell, Akon, Paul Okenfold, Afrojack, Pete Tong and NERVO. "It was absolutely amazing and beautiful beyond belief," a source tells Us Weekly of their vow renewal.

Guetta's "Turn Me On" music video, featuring Nicki Minaj, is nominated for Best Visual Effects at the MTV Video Music Awards, airing live from the Staples Center in Los Angeles on Sept. 6 at 8 p.m. EST. The collaborators are up against Katy Perry ("Wide Awake"), Rihanna ("Where Have You Been"), Linkin Park ("Burn It Down") and Skrillex ("First of the Year").
